Apparently men naturally want to harm others, and when they act more like mothers, they don’t want to. Cuz we all know that testosterone is what creates toxic masculinity :

“‘We think it’s a revolution,’ her colleague Karin Hallback Stigendal chimes in. ‘These daddies here, they’re very much closer to their feelings. They couldn’t harm another person. Children will change their minds, and that will be good for our society.’”

“I felt compelled to find out if I was imagining it, and quickly discovered an explosion of new research demonstrating the dramatic impact that fatherhood has on men’s hormones – along with their affect and talent for staying attuned. A 2011 longitudinal study of 624 Filipino men showed evening testosterone dropping by a median of 34 per cent in the first month after becoming fathers (the most extreme case saw a drop of 75 per cent). Levels of oxytocin, the so-called ‘cuddle hormone’, almost double in fathers between the time the mothers become pregnant and the first months of fatherhood. Prolactin, the hormone that triggers lactation in women, was almost a fifth higher in fathers of infants than in non-fathers. Fatherhood also physically alters the brain. In a 2014 study, researchers scanned men’s brains in the first month after their children were born, and then again after the fourth month. It turned out that gray matter grew in areas linked to reward, attachment and complex decision-making.”
